LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 
Polypodium heterocarpum (BI.) Mett. 
Todaya, alt. 450 to 900 m., Copeland 962,965,1251,1536. 
Camp Keithley; Luzon. 
Java, Celebes. 
Polypodium macrophyllum (Bl.) Reinw. 
On bases of trees in wet woods, Todaya, alt. 1200 m., 
No. 11293. 
Throughout the Philippines. 
Malaya to China and New Guinea. 
Polypodium vulcanicum Bl. 
Creeping in rock erevices, Mt. Apo, from 2400 m. alt. 
to the summit, No. 11536. ‘‘Cadayogan.” 
Colleeted here repeatedly; otherwise known in the 
Philippines only on Mt. Pinatubo. 
Sunda to Celebes. 
Polypodium caudiforme BI. 
Creeping on upper side of limbs, Mt. Calelan, alt. 2450 m., 
No. 11850. ''Cayop-yop." 
In a treatment of the ferns of Mt. Apo, I am unwilling to 
merge P. vulcanicum and P. caudiforme in P. Feei. The two 
forms are here quite distinct in appearance and in habitat; and 
I do not believe that the environment acting on the indi- 
vidual is entirely responsible for the difference in stature, 
form and structure. 
Mindanao, Negros. 
Malaya, Polynesia. 
Polypodium dolichopterum Copel. in P. J. S. 1, Suppl. 
(1906) 162.
